- Abstract
To improve the combustion randomness and enhance the launch stability of traditional fireworks, the compressed air was introduced to drive the firework projectile instead of the traditional gunpowder combustion process in this paper. A simulation model and C++ program of the compressed air launching the spherical firework projectile were established to simulate both the acceleration process of the spherical projectile in the barrel and its free flight process in the air. Results showed that the simulation model can effectively reflect the motion characteristics and laws of the spherical projectile driven by the compressed air. For a spherical firework projectile with a diameter of 50 mm and a mass of 105 g, a barrel with an initial volume of 50 mL and a projectile trip of 1 m can be employed. This spherical firework projectile can reach the desired altitude of 150 m and 200 m, when the launching angle was set at 65° and the initial gas pressure is 2.65 MPa and 3.85 MPa respectively. The research results can provide effective theoretical support for the research and development of the spherical firework projectile launching system driven by compressed air.
